>>>I suspect there is some little thing you aren't noticing. Are you positive the data sources and columns are paired up right? If you aren't viewing the Properties sheet with non-default properties only, try turning that on and viewing each grid column (column object and also the control stored in it) in turn. I bet something jumps out at you.

I am clear now. And in case you didn't see my posting on the cause of the problem, it had to do with the datasource, you are correct. I was setting the value in ControlSource after removing Text1 and adding EditBox. Once I moved the ControlSource to the proper place, the problem went away.
